Abstract

"APERFEIçOAMENTO INTRODUZIDO EM MéTODO PARA CERTIFICAçãO, APERFEIçOAMENTO INTRODUZIDO EM APARELHO DE COMUNICAçãO E APERFEIçOAMENTO INTRODUZIDO EM APARELHO DE REVEZAMENTO. Incluídos estão: um provedor de acesso GWS que marca o tempo presente preciso e o telefone portátil MS que realiza a comunicação de pacote através do provedor de acesso GWS e do servidor IP W. O telefone portátil MS adquire a informação de tempo a partir do provedor de acesso GWS no momento do início da comunicação com o servidor IP W e corrige, com base nesta informação de tempo, a marcação do tempo presente de seu próprio telefone portátil MS, de forma que este se torne mais preciso. Em adição, o telefone portátil MS decodifica um certificado de chave pública (um certificado eletrónico emitido pelo Escritório de Certificado C para o certificado de chave pública do servidor IP W) utilizando a chave pública do Escritório de Certificado C. Então, o telefone portátil MS avalia se está dentro do período de validade especificado no certificado de chave pública, utilizando o tempo presente corrigido de seu próprio telefone portátil MS.
